TC1224-3.0VCTTR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TC1224-3.0VCTTR is a fixed positive low dropout regulator manufactured by Microchip Technology, delivering a nominal output voltage of 3.0 V with a maximum output current of 100 mA. It operates within an input voltage range of 2.7 V to 6.0 V and features a typical dropout voltage of 85 mV at full load. The device incorporates CMOS construction for extremely low ground current, ensuring extended battery life in portable applications. It includes integrated over-current and over-temperature protection mechanisms.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'TR' indicates reel packaging when sourcing from distributors. Confirm that the manufacturer designation matches Microchip Technology Inc., as historical records may reference TelCom Semiconductor. Ensure the component meets RoHS compliance standards required for your assembly process before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this model when a 100 mA output capability is required, distinguishing it from the 50 mA TC1223 series. Verify that the system's minimum input voltage exceeds the sum of the 3.0 V output and the specified dropout voltage across the expected load range. Consider the SOT-23A package dimensions if board space is constrained.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the TC1223/TC1224 family of high-accuracy CMOS LDO regulators designed as upgrades for older bipolar regulators like the LP2980. The TC1224 variant specifically provides 100 mA output capacity compared to the 50 mA limit of the TC1223. Both share identical pinouts and feature sets, differing primarily in current handling capabilities.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The datasheet identifies the TC1107, TC1108, and TC1173 as alternatives for higher output current requirements (300 mA). No direct pin-compatible replacements are explicitly listed for the 100 mA class within the provided documentation.
